Description

Cleaning or application device with a sponge body and method for its production

The invention relates to a method for producing a cleaning or application sponge and to a cleaning or application device which is equipped with a corresponding sponge or sponge body.

For the production of cleaning and application sponges, such as those used today primarily in the household, it is known to first produce a relatively large block from a polyurethane foam with a cuboid or cube shape. The sponge is then worked out of this foam block by cutting and / or punching. If additional recesses are to be worked into the sponge or the edges of it are to be chamfered, the sponge must be subjected to a subsequent milling process. The known manufacturing process is disadvantageous in many ways:

On the one hand, the process is very complex and therefore expensive due to the large number of process steps to be carried out in succession. In addition, the foam blocks are usually not produced by the sponge manufacturers themselves, but bought from third parties, so that they must first be transported to the sponge manufacturer. In order to reduce the very large transport volume, it is known to compress the foam blocks, but a relatively large transport volume remains with a relatively low transport weight, so that the transport of the foam blocks is uneconomical. In addition, the foam blocks require a large storage space from the sponge manufacturer and lead to expensive storage.

When cutting out and / or punching the sponges and in particular when reworking them, there is a very high loss of material or waste, which is not only uneconomical but also highly harmful to the environment. The cutting, punching and milling processes only allow very limited shapes, in particular undercuts or physical configurations, e.g. Representations of animals or humans, are very difficult or not at all to be trained.

A major disadvantage of a sponge worked out from a block of foam is that the pores lying on the edges of the sponge are cut open, which is associated with a loss of stability of the sponge in these areas. When the sponge is used in practice, however, its edges and corner areas are required in particular for cleaning or application, so that the usage properties of the known sponge are insufficient in this regard.

For some applications it is useful and necessary, at least one side ren the sponge with a covering to kaschie ^¬. To this end, a blank is created to be laminated of the covering and this is then applied by means of a Flammkaschierverfahrens. However, this procedure is very labor intensive and also not harmless. One of the main disadvantages of the known sponges is the uniform pore or cell structure over the entire volume of the sponge. When a sponge is moistened and used for cleaning, the moisture is not only pressed towards the object to be cleaned or otherwise treated, but also flows onto the fingers holding the sponge and the palm of the user supporting the sponge. In this way, the cleaning liquid or the medium to be applied cannot be used in a targeted manner.

The invention has for its object to provide a method for producing a cleaning or application sponge with which it can be produced in a cost-effective and environmentally friendly manner, even in a complicated shape. In addition, a cleaning or application device with a corresponding sponge body is to be created.

This object is achieved with respect to the method in that the sponge body is foamed in a mold essentially to the final shape or design of the sponge, a solidified outer skin being formed on the outer surface of the sponge body during the foaming process, at least in some areas, but in particular on the entire outer surface becomes.

In this way, the sponge body is given the desired shape during the foaming process, so that little or no rework is required. Compared to the known sponge production, the total number of process steps is significantly reduced, so that the sponge can be produced in a cost-effective manner. The above problem with the transportation and warehousing of the Foam blocks are connected can be completely avoided in the method according to the invention. Since the shaping of the sponge takes place according to the invention through the mold cavity of the molding tool and not through post-processing with material removal, the material losses can be kept very low.

The formation of the solidified outer skin on the outer surface of the sponge body can be achieved in that the process parameters, for example the tool temperature, the cooling, the foam density, the foaming pressure etc., which can be controlled by the composition of the plastic material, are adjusted so that the closed, solidified skin of the plastic material is formed on the outer surface of the sponge body. The solidified outer skin increases the stability of the sponge body, the outer skin in the areas of the sponge body which are used for the product being subsequently opened or removed at least in regions, which can be done, for example, by milling, cutting, grinding, peeling, sandblasting or dissolving.

The inside of the sponge body preferably has a closed-cell structure which can be opened in some areas in a subsequent method step. In this way, it is possible to leave certain areas of the sponge body closed-celled, as a result of which these areas have increased stability on the one hand and on the other hand prevent the liquid in the sponge body from escaping at these areas during use. The closed-cell foam is preferably only opened in those areas of the black body that are used for the product, so that a targeted exit of the liquid or the medium to be applied is possible from the sponge body. The opening of a closed-cell foam structure is known per se and can be done, for example, by mechanical blasting by means of pressure, the so-called crushing.

The areas of the sponge body that remain unopened and thus have a higher strength can serve as handle sections for the user. In particular, those areas of the sponge body which are intended to directly or indirectly hold the sponge body on handle parts, handles, handles, etc. can also remain closed-pore.

The foaming process in the mold generally uses release agents which are removed in the method according to the invention by opening the closed-cell structure on the surface or opening the outer skin without additional measures.

The edge strength of the sponge body can be increased not only by increasing the density of the foam material, but also by suitable temperature control in the Schäu tools. If the foaming reaction takes place in a closed mold, for example tempered to 30 ° C to 60 ° C, and more in the mold cavity

Plastic material is filled in as necessary, this material cross-links with compression to a harder structure with the denser outer skin, which continuously merges into a cellular core. Through a suitable choice of temperature and material mixture input into the mold cavity, targeted foam structures and surface structures with high edge strengths can be achieved in this way. If more stable holding or grip sections or sealed areas are to be formed on the sponge body in the aforementioned manner, the outer skin is not opened in these sections of the sponge body.

A flexible polyurethane foam has proven itself as the material for the sponge body, the foam density of which can be in the range from 25 kg / m ³ to 80 kg / m ³ . In particular, a polyester-PUR foam can also be used.

In a further development of the invention it can be provided that the sponge body consists of several differently structured sponge body sections. The sponge body sections can be prefabricated and then joined together by gluing or welding.

A preferred production possibility is given in that the mold cavity of the mold is divided into several chambers with one or more partition walls, in particular in the form of slides. A foam material is filled into each chamber and reacted. Before the end of the foaming reaction, the partitions are removed, for example by pulling the slide, whereby the material in the individual chambers can bond. The chambers can be completely separated from one another by the partitions, but it is also possible, for example, for the chambers to be connected in predetermined sections, for example in the central region of the mold cavity, so that in this region a connection or a mixing of the two foam structures is unimpeded takes place, while in the outer circumferential area of the sponge body there is a clear delimitation of the different structural areas due to the partition walls located there. In the central area of the sponge body, which is preferably the predominant volume of the sponge body encompassed, an intensive connection of the two structures is created, while in a relatively small edge or circumferential area an exact delimitation of the two structures is possible over a small depth. The sponge body can also be constructed from several layers of the same or different dimensions.

In a preferred development of the invention it is provided that a storage chamber for a cleaning medium or a medium to be applied is formed in the sponge body with at least one filling opening running to the outside of the sponge body. The medium to be applied, which can be a liquid, a powder, a powder, tablets or capsules, can be arranged in the storage chamber, the medium being used when the

Sponge body is supplied to the working or application surface of the sponge body, which is achieved either by the open-cell structure of the sponge body in this area and / or by additional application channels, which can be drilled, for example. The method according to the invention of foaming the sponge body in the mold leaves a great many possibilities for the design of the storage chamber in the form of a cavity made in the sponge body. If a prefabricated handle part, in particular made of plastic, is attached to the sponge body, this can contain the storage chamber for the medium to be applied or at least form it together with a surface of the sponge body. For this purpose, the handle part can have a filling opening through which the medium to be applied can be filled or refilled into the storage chamber. The filling opening can be closed by a closure, which can be a molded cover, stopper or a similar closure element. In a preferred embodiment, the storage chamber for the measurement to be applied is dium formed in the space between the sponge body and the attached handle part.

If a section of the sponge body remains unopened to form a holding section, it can be grooved, profiled or structured on the outside in order to make it easier for the user to grasp the sponge body and to guide it during use.

If a separate handle part is attached to the sponge body, this is fastened in the above-mentioned manner in particular to an unopened section of the sponge body, wherein preferably a locking or tensioning of the sponge body is provided in the handle part so that the handle part also worn

Sponge body can continue to be used and a new sponge body can be added. In this case, the sponge body can either completely fill the handle part, but it is also possible to leave a space in the interior of the handle part above the sponge body, which can serve, for example, as a storage chamber for the medium to be applied in the manner mentioned above.

In a development of the invention it is provided that an inner bag is embedded in the sponge body, which is accessible from the outside of the sponge body. In particular, this inner bag is designed as a glove, for example made of rubber or plastic, so that a user can slip the glove over his hand and thus wear a sponge body attached to his hand, in the case of which

Use it does not come into contact with the medium to be applied or the cleaning liquid.

The molded foam process according to the invention allows the formation of further elements on the sponge body. For example a suspension eyelet can be formed on the sponge body, or it is also possible to captively integrate a closure plug for the filling opening of the storage chamber into the sponge body. In addition, a handle part can be connected to the sponge body, for example via a hinge joint, and can be produced together with it, so that the handle part is only pivoted into a position fixed on the sponge body after removal from the mold.

The working or application surfaces of the sponge body can be structured. The surface structures can serve both a cleaning or application function or information or decoration. The structuring can be designed to be relatively flat and planar or also pin-like or bristle-like. The protruding surface areas can remain closed or can also be opened by removing the outer skin. The surface of the sponge body can be influenced by further measures such as polishing, electroplating or eroding the mold cavity.

The sponge body can be given an antimicrobial treatment. For this purpose, antimicrobial agents are introduced into the starting material to be foamed or into the cavity of the molding tool. The antimicrobial active ingredients can in particular be water-soluble active ingredients such as xylitol, chlorhexidine salts or cetylpyridinium chloriol. Retrofitting of the sponge body is also possible by impregnating it with antimicrobial agents or by adding the antimicrobial agents in liquid, pasty, powdery or solid form into cavities of the sponge body. It can be a question of separate cavities provided specifically for this purpose. However, it is also possible to use the antimicrobial agents tel to the detergents, especially in the form of liquid detergents. If the anti-microbial agents are introduced into a cavity of the sponge body with walls that are not or only slightly open, the agent remains effective over a long period of time. This also applies to cleaning and application media. The closed outer skin in the handling area helps to avoid undesired leakage and promotes the targeted use of these agents.

The sponge body can be provided with a plurality of chambers which are separated from one another and in which means are accommodated which can react on contact with one another. These agents are brought together by the cell structure of the sponge body and / or the compression of the sponge body when in use. In this way, continuous dosing through the cell structure or forced dosing caused by the pressure on the sponge body is possible.

The areas of the sponge body in which the largely closed outer skin remains can be provided with information and / or decorations by sandblasting, etching, printing, screen printing, inkjet printing or lasers.

In particular, it can be provided that the sponge body is provided with a covering in sections on its outer surface. This can be achieved in particular by placing the coating in the mold before the sponge body is foamed. This is associated with the particular advantage that the lamination material can also be inserted in part or in several pieces and distributed on the handling, working or application surface of the sponge body. The laminating materials can result the good adhesion of PU foams to all possible materials can be selected almost arbitrarily. It can be abrasive films, fabrics, sprayed sheet materials made of elastomer, for example with cams, pins or bristles, or also silicone bristles. Corresponding inlays at corners and edges of the molded foam sponge body are particularly advantageous. Abrasive materials can also be applied in the inlays or directly on the sponge body. Due to the foaming of the sponge body, objects made of materials without affinity can be embedded in it by foaming, which can be, for example, hanging loops or metal eyelets.

A cleaning or application device according to the invention comprises a sponge body of the abovementioned construction, it being provided in particular that a grip part is attached to the holding section of the sponge body.

Fig. 1 shows schematically a mold for producing a sponge body according to the inventive method. The molding tool comprises two mold halves 11 and 12, which define a mold cavity 15 between them. Via a feed channel 16, a foaming plastic material, which is in particular a flexible polyurethane foam, can be introduced into the mold cavity 15 and foamed there, as indicated by the arrow M. The size and shape of the mold cavity 15 corresponds essentially to the final shape or design of the

Sponge body. After opening the molding tool, a sponge body 10 results with an inner, uniform closed-cell structure and a continuously closed, solidified outer skin 13, which is relatively stable and is selected by the setting of the process parameters. meter during the foaming process on the outside of the sponge body 10, as shown in Fig. 2. The outer skin 13 can be broken open in sections, so that the sponge body 10 shown in FIG. 3 results with a continuous inner closed-cell area, the lower area of which is freed from the outer skin 13. The remaining solid outer skin 13 can be used as a stable handle section for the user or for attaching a separate handle part.

The sponge body 10 according to FIG. 4 differs from the sponge body according to FIG. 3 in that the sponge body 10 has a subsequently opened cell structure in its lower region 10b, while the upper region 10a remains closed-cell and is surrounded by the solid outer skin 13 , The closed-cell region 10a has greater spatial stability than the open-cell region 10b and can serve as a handle or shark section for a user. In addition, inward recesses 13a are formed in the lateral edges of the upper region, which make gripping the sponge body 10 easier or can be used for the form-fitting attachment of a separate handle part 14, as is indicated in FIG. 5. The hood-like, separate handle part 14, which is open at the bottom, is placed from above onto the solidified section of the sponge body in such a way that its side parts snap into the recesses 13a under elastic deformation, so that the handle part 14 is held firmly on the sponge body 10. The assembled state of the handle part 14 is shown in FIG. 6, the sponge body completely filling the interior of the handle part 14. Alternatively, however, it is also possible that the interior of the handle part 14 is only partially filled by the sponge body 10, as shown in FIG. 7. FIG. 8 shows a sponge body 10 with a section that is open in the lower area or freed from the outer skin, while the outer skin 13 has remained in the upper area. A recess is formed on the top of the sponge body 10 and forms a storage chamber 17 for a cleaning agent or a medium to be applied. A hinge joint 18 is integrally formed on the sponge body 10, a handle part 14, which is completely surrounded by a solidified outer skin and on its surface facing the top of the sponge body 10 has a stopper-like projection 14a, which can seal the storage chamber 17 from above, if that Handle part 14 is pivoted about the hinge joint 18 and comes to rest on the top of the sponge body 10. In the alternative embodiment shown in FIG. 9, a sealing plug 20 is molded onto the sponge body 10, which is connected to the sponge body via a connecting web 19 and can close the top-side filling opening of the storage chamber 17.

10 to 12 show sponge bodies with a structured surface. 10, the sponge body 10 has a plurality of projecting flat areas 21 of relatively low height on its lower working surface. If the sponge body

10 is removed from the molding tool, it is completely surrounded by a solid outer skin 13. This is only opened in the area of the protruding areas 21, while the sections of the lower work surface lying between the areas 21 remain closed by the outer skin 13.

11 shows a broom formed from a sponge body. For this purpose, the sponge body is cantilevered on its underside with a large number of the fingers 22, which are freed from the outer skin 13. In the upper area, in which the outer skin 13 has remained, the sponge body 10 is encompassed by a holding part 23 which is connected to a broom handle 24.

The sponge body acc. Fig. 12 has on its underside protruding projections 25 which are in turn provided with bristle-like fingers 26 on their underside. The projections 25 including the fingers 26 are freed from the stable outer skin 13. In the upper area of the sponge body 10, it is surrounded by a separate stiffening grip part 14.

Fig. 13 shows a sponge body 10 which carries a prefabricated cap-like handle part 14 in its upper region, wherein between the top of the sponge body 10 and the handle part 14, i.e. in the interior of which a storage chamber 17 is formed for a medium to be applied. The handle part 14 has an integrally formed pivotable flap 14b with which a filling opening 27 of the storage chamber 17 can be opened or closed as desired.

The lower region of the sponge body 10 is opened in the aforementioned manner and is freed from the outer skin. A plurality of channels 29 extend between the storage chamber 17 and the opposite application ^surface 28 of the sponge body 10. The channels 29 can be dimensioned and aligned such that powdered or powdery substances can be supplied and applied from the storage chamber 17 to the application surface 28 , For reasons of stability, the upper side of the sponge body overlapped by the grip part 14 is not freed from the outer skin 13 except for the mouth openings of the channels 29. If the user puts pressure on the sponge body 10, this leads to one Swirling the powder in the storage chamber 17 and thus loosening it.

14 shows a sponge body 10, in the upper region of which the stable outer skin 13 has remained. A gap or slit 29 is formed on the upper side of the sponge body and can optionally be connected to a storage chamber for a medium to be applied, which is formed in the interior of the sponge body 10 in a manner not shown. If a storage chamber is formed, it is accessible from the outside via the slot 29. The slot 29 on the top of the sponge body 10 is closed in the normal state of the sponge body due to the inherent elasticity of the foam material. In order to fill or refill a medium into the slot -29 or the storage chamber, the user must pressurize the sponge body 10 from opposite sides, as shown by the arrows P in FIG. As a result, the sponge body 10 deforms such that the slot 29 opens and makes it possible to fill in the medium, as is also shown in FIG. 15.

16 shows a sponge body in a kidney-shaped configuration which tapers slightly at one end. Here, too, the sponge body is in its lower section

10b is opened while it is opened 10a un ^¬ in its upper portion and carries a stabilizing outer skin. 13 Handle recesses 13a are molded into the sides of the sponge body 10. A suspension lens 30 is integrally formed on one end, which is only slightly foamed and thus has increased stability. 17 shows, the sponge body 10 has in its interior a storage chamber 17 for cleaning agents or a medium to be applied, which via a labyrinth channel 31 serves as a closure, is connected to the top of the sponge body.

18 shows a sponge body 10, which is open in its lower region 10b and has a molded-in depression on its upper side to form a storage chamber 17. In the upper, unopened area 10a of the sponge body, a circumferential latching projection 32 with a corresponding latching recess is formed, so that a separately prefabricated handle part 14 with molded handle 14a can be snapped onto the top of the sponge body 10, the top of the sponge body and thus the storage chamber 17 covered like a lid. The handle part 14 has an integrally formed flap 14b, which can be opened according to FIG. 19, so that a cleaning agent can be filled into the storage chamber 17 of the sponge body 10 from above.

In the exemplary embodiment shown in FIG. 20, the outside of the sponge body 10 is laminated with coverings which are inserted into the mold cavity of the mold before the foaming process. In the exemplary embodiment shown, both a slightly abrasive coating 33 with a small surface structure and, in addition, a strongly abrasive coating 34 are applied. Alternatively or in addition to this, the sponge body 10 can also be flocked. The sponge body 10 according to FIG. 20 is further characterized in that an insertion opening 35 is formed in its central region, into which a storage cartridge 36 can be inserted, which contains a cleaning agent or a medium to be applied. When the cartridge 36 is empty, it is either replaced with a new cartridge or pushed out of the sponge body 10 and refilled, as shown in FIG. 21. 22, the sponge body 10 has a bag-like shape and can be used as a cleaning glove. A storage chamber 17, into which the cleaning agent can be poured, is divided on one side via a partition 37. The storage chamber 17 can be closed at the upper end of the bag-like sponge body by pressing projections 38 formed on the side wall of the sponge body into corresponding receptacles 39 of the dividing wall 37 with elastic deformation, as is shown in FIGS. 23 and 24.

So that the user does not wet his hands when using the sponge body, an inner bag in the form of a glove 40 can be embedded in the sponge body 10 and is accessible from the outside of the sponge body. In addition, a storage chamber for cleaning agents is formed in the sponge body, which can either be opened (FIG. 27) or closed (FIG. 26) via a sealing plug 20, which is connected in one piece to the sponge body 10 via a connecting web 19.

According to the configuration shown in Fig. 28, on the underside, i.e. The working surface of the sponge body is formed with recesses 41, in each of which a bristle bundle 42 is arranged, which is preferably attached to the sponge body at its inner end. In the normal state of the sponge body, the bristle bundles are completely received in the recesses 41 of the sponge body. If, however, the foam material of the sponge body is compressed during use, the bristle bundles emerge from the underside of the sponge body, whereby a cleaning effect is enhanced.

29 shows a sponge body in which the stable outer skin 13 in the region of a side edge of the lower arm. worktop remains and thus causes a reinforcement of the edge. Alternatively, the area of the edge can also be flocked or provided with an insert when the sponge body is foamed.

30 to 34 show representational configurations of a sponge body, as can be achieved with the foaming process according to the invention. Both animal representations, such as the mouse shown in FIG. 30 or the frog shown in FIG. 34, as well as the representation of a mushroom according to FIG. 31, a face according to FIG. 32 for a cosmetic pad or also one Pot brush with the representation of a cook according to FIG. 33 possible.
